dūtā yātvā yamāntikam
yama-rājñe yathā sarvam
In this verse the word pratyuditāḥ is very significant. The servants of Yamarāja are so powerful that they can never be hindered anywhere, but this time they were baffled and disappointed in their attempt to take away a man they considered sinful. Therefore they immediately returned to Yamarāja and described to him everything that had happened.
